It's Always Sunny in Philadelphia is an American comedy series about four friends in their late 20s with clear sociopathic tendencies who run an unsuccessful Irish bar, "Paddy's Pub," in South Philadelphia. The series deals with a variety of controversial topics, including abortion, gun control, physical disabilities, racism, sexism, religion, the Israeli/Palestinian situation, terrorism, transsexuality, slavery, incest, sexual harassment in education, the homeless, statutory rape, drug addiction, pedophilia, child abuse, mental illness, gay rights and dumpster babies.

Laden with laugh-out-loud moments. ... Just as "Curb Your Enthusiasm" so boldly and brilliantly attacks taboo subjects, so does "It's Always Sunny in Philadelphia," though the humor is spread from one clueless, self-centered ass to four, clueless, self-centered slackers. [4 Aug 2005]

The laughs, as they should, come fast and hard from the characters, somehow likable in their social ineptitude. But if you can't see the situations - irreverent barely begins to describe them - as absurd, you might not have a lot of fun. [4 Aug 2005]

In its eighth season, It's Always Sunny doesn't try very many new things, but the writers are smart enough to know not to mess with a successful formula, and the series carries itself with an air of aplomb that many comedies rarely come close to exhibiting.

What makes it palatable is that it is often laugh-out-loud hilarious. If Seinfeld broke down a few barriers when it came to subject matter in a sitcom, Philadelphia gleefully smashes right through them. [3 Aug 2005]

It's more like Seinfeld reconceived for the slacker sensibility of a director like Kevin Smith or Richard Linklater. And that's what's wrong with the show: It's hard to shake the feeling that it's just someone's project.
